AUGUST HEINE, OF SILVER CREEK, NEV YORK.

FLOUR-BOLT.

SPECIFICATION formingJ part of Letters Patent No. 346,282, dated July 27, 1886.

Application filed February QG, 1886.

To @ZZ whom it may concern.:

Be it known that I, AUeUs'r HEINE, of Silver Creek, iu the county of Chautauqua and State of New York, have invented new and useful Improvements in Flour-Bolts, of which the following is a specification.

This invention relates principally to an improvement in that class of Hour-bolts which are composed of a revolving reel provided on the inner side of its bolting-surfaee with elevating ribs or contrivauces whereby the material under treatment is elevated and carried around with the bolting-surfaee, thereby distributing the material constantly over the greater portion of the bolting-surfaee.

The object of my invention is to provide means for separating and removing the light floating impurities from the more valuable particles, thereby improving the quality and color of the bolted material, to increase the bolting capacity and to render the machine more efficient in other respects.

My invention consists to that end of the improvements which will lbe hereinafterl fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a longitudinal sectional elevation of a ilourbolt provided with my improvements. Fig. 2 is a cross-section of the same. Fig. 3 is a fragmentary elevation of the inclined portion of the defleetor. Fig. et is a sectional view of the reel-head located at the feed end of the reel. Fig. 5 is a fragmentary sectional View of said reel-head and connecting parts 011 an enlarged scale. Fig. G is an elevation of the movable ring at the head of the machine.

Like letters of reference refer to like parts in the several figures.

A represents the stationary case of the machine; B, the revolving reel, and b the shaft on which the reel is mounted, and which is journaled in bearings C C. The reel-frame consists of a head, D, located at the feed end ofthe reel, a head, E, located at the tail end of the reel, and longitudinal ribs F, connecting the heads D and E on the inner side of the bolting-cloth c. The latter is stretched around rings f, which rest against short pro jeetions f', formed onthe outer sides of the ribs F, so that open spaces g are formed be- Serial No. 193,350. (Nomodel.)

tween the ribs F and the bolting-eloth c. The head D at the feed end of the reel is provided with a central opening, 7t,which is surrounded by a forwardly-projecting collar, H.

I represents a spider or arms, which connect the head D to a hub, t', by which it is secured to the shaft Z1.

J represents aring or eollar,which fits snugly within the c ollar H, and which is attached to the rear side of the front wall, a, of the ease of the machine. The ring J is provided with a flange, j, which rests against the wall a, and with radial arms k, seated in sockets K,whieh are secured to the wall a. The sockets K are somewhat deeper or longer than the arms lr, so that each arm is capable of a certain longitudinal movement in its socket, whereby the ring J is enabled to adjust itself on the ease to the position of the reel-head D when the relative position of the reel and case becomes altered by shrinkage of the wood or from other causes. This adj ustability of the ring J prevents the parts from binding on each other, and insures a snug fit of the collars H aud J at all times.

L represents the feedspout, which delivers the material to be bolted into the chamber formed by the ring J ,which latter is provided with an inclined bottom, Z, whereby the material is directed into the reel through the opening h of the head D.

m represents an internal screw-th read formed in the collar H in such manner that the rotation of the screw-thread with the reel will cause any particles entering between the collars H and' J to be worked backward into the reel.

N represents a deiector or bridge arranged lengthwise in the upper portion of the reel and made convex on its upper side and concave on its lower side, so as to form on its under side a passage or chamber, N. The deilcctor N is preferably curved on one side concentric with the ascending side of the reel, as shown at n,

and is inclined at its opposite side, as shown 9 at n. The inclined portion n is provided on its'outer side with inclined deIlecting-boards o, whereby the material falling on this inclined portieri is deliected toward the tail of themachine. The front end of the delector N is supported on the shaft b by arms Panda-hub,

p, in which latter theshaft Z) revolves. The` rear end of the deiiector is provided with arms Q and a hub, q, which latter is secured by a set-screw, or otherwise, to an extension, r, of the bearing C. is held stationary within the reel.

The head E at the tail end of the reel is provided with a central discharge-opening; s,- elevating ribs s', and a deiiecting cone, si, whereby the tailings are discharged from the reel and delivered into the discharge-spout1T` f in a well-known manner.

The material to be bolted is introduced into the reel through the spout L in such quantities that the reel is kept well loaded, andf" thefeed-spout ismade so large that copiousf quantities of air are permitted-to -enter "the reel with the material to be bolted. F elevate a largeportion ofthe materialA which lies upon the bottom of the reel and distributethe same constantly over a large-portionv ofthe inciting-surface. A portion of '-the elevated material runs back over the bolting-surfacel Another portion is-elevated and is bolted. aboveI the deilector N and vfalls on thesama The deilector prevents this portion of thema@ inv which the light doa-ting impurities can accumulate and separate from the heavier and' more valuable portions of the material. The cham#I -ber-N, formed on the underside lof-the =d'el'-- iiector N, is protected against the disturbing action of particles falling through the same,

. and the light iloating impurities therefore remain in this comparatively quiet space and-- pass slowly with the air toward the "tailendL of the machine and escape finally through the discharge-opening s wit-l1 the tailings; The

heavier and -more valuable particles` whichmay have become suspended in the-air-current passing through the reel, settle in this chamber N', and are returned to the massoff'material `resting on the bottom of the reel.v By this means the reel can be full yloaded and 4a largeV portion of the material can becOnStantly-kept in contact with the bolting-clothwithout cans ing specks and other light-impurities'to'passthroughthe bolting-cloth, thereby increasing the bolting capacity and at the same time improving the quality of the bolted-mate` rial. An air-current sufficient to remove the light impurities is caused by the revolution of the reel and its feed and discharge de# vices; but, if desired, a fan or other air-propel'- ling device may be employed Afor the purpose.AV

The material which falls from the elevatingmaterial is loosened, and the light impurities By this means the deiiector N The-ribs are-causedto-become suspendedin the air,

while" the' heavier valuable particles are caused to pass through the bolting-cloth, thus enabling the upper` portion of the reel to per- 73 form a large share of the operation of bolting. {Phe-concentric portion n of the deflector or bridge N, which is arranged opposite the ascending side of the reel, confines the falling material in a narrow space, where itis kmet by the ascending ribs and gently' dashed vor thrown against the bolting-cloth. Part ofthe `materialI passes through the open spaces g be'- tweenl the ribs F and the bolting-cloth, whereby the bolting capacity of the reel is increased, and the material is prevented from accumulating on theribs to such an-extent`as tointerferewith fthe dashing 'action' of the samef Theinclined portion" n' of the deflector, which? is arranged-oppositethe descending portion of -thereel, di'rects the descending material againstfthe bolting-cloth, and-the-` deecting-boardso'give the material'a tendl ency toI movetowardthe tail of the machine.- The two parts of the-deflector diverge downiwardly and.y form a bridge-resembling an archi;
